The Minecraft Overviewer is a command-line tool for rendering high-resolution
maps of Minecraft worlds. It generates a set of static html and image files and
uses the Google Maps API to display a nice interactive map.

The Overviewer has been in active development for several years and has many
features, including day and night lighting, cave rendering, mineral overlays,
and many plugins for even more features! It is written mostly in Python with
critical sections in C as an extension module.

It does not run fast. Because of the high level of detail, initial renders of
a world can take some time. Expect minutes for medium worlds, hours for large
to huge worlds. Subsequent renders are much faster due to the caching.

Also note that speed is improving all the time. We continually make efficiency
improvements to The Overviewer. Besides, for the level of detail provided,
our users consider it worth the time!

The Overviewer is not targeted at end users. We mainly see Overviewer fitting
in best with server operators, rendering their server’s map for all users to
view.

You are welcome to use The Overviewer for your single player worlds, and it
will work just fine. However, since the only interface is currently command
line based, you will need to know a bit about the command line in order to
operate The Overviewer.

IF YOU NEED HELP COMPILING OR RUNNING THE OVERVIEWER feel free to chat with
us live in IRC: #overviewer on Freenode. There’s usually someone on there that
can help you out. Not familiar with IRC? Use the web client. (If there’s no immediate
response, wait around or try a different time of day; we have to sleep sometime)
